I recently got my first HT system (a Yamaha HTR5550 and Infinity speakers). I mainly got it to listen to movies in surround sound and it sounds great. However, I'm not sure how to get the best sound possible when listening to music on CD. The receiver has a couple of modes like "hall" or "rock concert" which I think sound wierd. Then there is the "dolby/pro logic" setting whick sounds ok and there is also a setting which sends all the sounds equally to all 5 speakers. The manual does not do a good job in my opinion of recommending which modes are designed for music. Should I expect to get a surround effect from a CD where different sounds are assigned to different channels. Are CDs recorded to deliver in surround, or are they designed for the sound to come mainly from the center front speakers?
